Alert Simulator

Features
Read full description

This app generates simulated alerts that could happen in a plane during cruise for pilot training. You can use the app in two ways: You can generate a random simulated alert at any time by pressing the Run One Now button. If you enable notifications, you can select a duration for cruise and frequency, press start flight and receive the notification in the background while doing other tasks, for example on your electronic flight bag. If you didn't enable notification you will just receive one simulated alert immediately. If you receive an simulated alert via a notification, you can click on it to see its detail on the app. The simulated alert can be either a situation, like an engine failure or a crew alerting message on your avionics, and you should determine and review all the steps required to handle the situation, identify and run checklists, information in pilot handbook, review the actions you should take. It relies on a predetermined database of alerts corresponding to the plane you select. Currently only two planes are available. The goal is for you to regularly go through the motion required for managing alert, so should a real alert happens it will be automatic. This app is open source on GitHub.

Daily maths practice, built by a Muslim family. Number Blast is the maths app we couldn't find — so we built it. Real practice, real characters, and children who finally see themselves on the screen. BUILT FOR OUR CHILDREN Number Blast is the first maths game created from the Black American Muslim community — built by a family who wanted their children represented in the tools they learn from. Dr. Fatimah — the Doctor Luqman — the Tech Genius Jahdari — Karate & Maths Wizard Timika — the Professor Eurila — the CEO Representation isn't a feature we added. It's the reason we started. Every child deserves to see themselves as a creator, not just a consumer. HOW IT PLAYS Solve to blast. Every correct answer clears a problem before the stack reaches the fire. Miss too many and it's over — so speed and accuracy both matter. Simple to pick up, tough to put down. This isn't a worksheet with a cartoon on top. It's real maths wrapped in real gameplay — the kind that makes children lean in, lose track of time, and ask to practise again. MORE THAN A GAME Daily Number Cross — a fresh maths puzzle every single day. Fill the grid, beat the challenge, come back tomorrow. Blast Stacks, your way — switch between Starters and Advanced as speed and confidence grow. Video Lessons — lessons that break down the maths behind the game, so fast answers come from real understanding, not guessing. QuestUp Cards — a taste of the wider QuestUp world as you play. A CHALLENGE FOR EVERY LEVEL From beginners finding their footing to advanced players proving they're the fastest, Number Blast scales across ages and skill levels. Start where you're comfortable, then climb wave after wave as the challenge grows with you. FOR PARENTS & EDUCATORS Sharpens mental maths, speed, and focus Challenge levels that grow with your child Screen time that actually builds skills Safe, engaging, and made with intention A FAMILY MISSION All praise is due to Allah first. Number Blast started as a family project — parents and children building something together that we couldn't find anywhere else. Eurila, a character we greatly appreciate, carries the name of a close friend and member of our community whom we lost. May Allah have mercy on her. Our children will grow up knowing her name, inshaAllah. Today it's part of QuestUp, a growing world of learning built to inspire the next generation, especially students of colour, to fall in love with learning through play. This is just the beginning.
